Title: Method and device for concreting underwater structures, preferably tunnels
Inventor: OFENSTEIN JOSEF
IPC: E02D29/077
Filed: 1981-11-09
Abstract: In a method of concreting underwater structures, preferably tunnels, a trench is excavated, a bed plate of underwater concrete is cast, and a steel caisson is connected at its bottom area to the bed plate in a sealing manner. The caisson is then pumped empty and the structure is concreted on the bed plate by means of placed formwork. In order to propose a less complicated and therefore more cost-effective method of producing underwater structures which leaves the ground-water regime essentially unimpaired, the flooded caisson (4) is set down on the pre-concreted bed plate (3) and its bottom end face is sealed off from the bed plate (3). After the caisson (4) is pumped empty, the inner formwork (22, 23) is attached and the structure (1) is concreted between the inner formwork (22, 23) and the inner wall of the caisson (4) as outer formwork. <IMAGE>

Title: Method of loading pressure-gas tanks for storing hydrogen
Inventor: HALENE CLEMENS DIPL ING
IPC: F17C11/00
Filed: 1981-12-03
Abstract: The invention relates to a method of loading pressure-gas tanks used for storing hydrogen, the method essentially consisting in the fact that, when the mass to be stored is poured into and compressed in the tanks, the tank wall is acted upon by pressure from outside, and that this admission of pressure also takes place during the loading with hydrogen. This is intended to ensure that deformations of the tank wall through expansion of the mass to be stored or when feeding the same into the tank are avoided. <IMAGE>

Title: Process and equipment for treating stagnant waters
Inventor: KRONIG REINHARD
IPC: C02F7/00
Filed: 1981-12-22
Abstract: The process and the equipment (1) are intended to allow, in particular selectively, the aeration of deep water, the forced circulation or the removal of deep water from stagnant waters, air being introduced by the action of suction in a water stream delivered upwards in the water body. For this purpose, the equipment (1) has a vertical riser (7, 12) and, arranged in series, a mechanical pump (9), a water jet compressor (10) and an air-lift pump (11, 12). The suction part of the water jet compressor (10) is connected to an inlet air line (11) leading to the open atmosphere. A part water stream is generated by means of the mechanical pump. In accordance with the principle of the water jet pump, the part water stream is utilised for introducing air. The required rate of water is obtained by means of the air-lift pump effect. The water provided with air is either returned to the depth of the lake by means of a drop line system (15) or discharged to the upper layers of the lake by means of a pipe arrangement, which can be placed on top of the chamber (13), or is led away. <IMAGE>
Patent DE-3205312-A1 (DE)
Title: Electronic soundproofing-system window
Inventor: HEHEMANN GUENTER
IPC: E06B5/20
Filed: 1982-02-15
Abstract: Electronic soundproofing-system window, on which electromechanical transducers register the soundwaves acting on the outer pane from outside and feed them as a control current to an electronic amplifier, from which the working current obtained thereby by amplification is fed to other electromechanical transducers which engage on the inner pane of the soundproofing-system window and which bring this to a standstill in vibration terms, with the result that sound deadening of the outside noise in relation to the room side of the soundproofing-system window is achieved. The electromechanical transducers can consist of piezoelectric crystals or piezoceramic blocks, the dimensions of which are such that they slightly spread apart the two panes of such a soundproofing-system window, thereby producing between piezoelectric elements, on the one hand, and the two panes, on the other hand, an alternating mechanical stress state, as a result of which the piezoelectric elements can act on the inner pane in a mechanically vibration-damping manner and, with an optimum control of the electronic soundproofing system, in a vibration-deadening manner.

Patent DE-3218058-A1 (DE)
Title: Appliance for decanting free-flowing substances, in particular for loading and unloading tankers
Inventor: ROEPER RUDOLF PROF DR ING
IPC: B67D9/02
Filed: 1982-05-13
Abstract: Known embodiments of loading appliances for free-flowing substances consist of extension tubes which are connected to one another in an articulated manner and are fastened to a supporting column in a horizontally and vertically pivotable manner. The moment distribution is produced by a counterweight which is pivotably linked and is adjusted by means of a tension-medium drive as a function of the relative position of the outer extension tube. If the tanker leaves the range of movement of the loading appliance due to drifting, a quick-disconnecting device breaks the connection to the ship. Due to an excess counterweight force then released, both extension tubes would swing up, so that a controlled retraction movement has to be effected by the supply of energy to avoid collisions. The invention describes a kinematic arrangement in which the loading appliance, after the disconnecting operation, moves back without external-energy supply only under the drive by the counterweight on a collision-free path into a position similar to the inoperative position. To this end, normally freely rotatable central discs mounted on the central swivel spindle are fitted into the moment-distributing tension-medium drive, which central discs are locked against rotation during the disconnecting. When the extension tubes swing up, the strands of the tension-medium drive wrap themselves around the drive and force a relative movement drawing in the counterweight and the outer extension tube.

Title: Process for detecting breakdowns in an electrostatic filter
Inventor: ALIG FRANZ DIPL ING
IPC: B03C3/68
Filed: 1982-05-26
Abstract: For regulation of an electrostatic filter which is supplied from an alternating current mains via a rectifier, a high voltage transformer and a regulating unit, the process compares a voltage value with a reference value and uses deviations from the reference value to control the voltage regulating means. The voltage difference between two successive measurements is used as the voltage value, and the voltage difference of the preceding half wave at like phase is used as the reference value. The difference of the absolute values of the two voltage differences is ascertained and is compared with a value X which determines the response sensitivity.

Patent DE-3222511-A1 (DE)
Inventor: REINHOLD ALFRED DIPL ING
IPC: H01J35/06
Filed: 1982-06-16
Abstract: In an X-ray tube having a glow cathode for emitting an electron beam, an anode, focusing and deflecting coils and a target in an evacuated envelope, the cathode is a U-bent filament the dimensions of which are large in relation to the electron emitting area. The cathode is heated by passing electric current through it and is differentially cooled so that a small surface area at the site of electron emission is at a substantially higher temperature than remaining surface areas of the cathode. Cooling is effected by a thick-walled cylindrical grid which surrounds the cathode and has at its outer end an annular inward projection which absorbs heat rays from the cathode. The grid has a funnel-shaped outer end surface having an included angle of about 100 DEG  to 140 DEG . The electron emitting surface of the cathode lies approximately in a plane defined by the inner peripheral edge of the funnel-shaped end surface of the grid. The electric field applied to the cathode has its highest value at the small electron emitting surface of the cathode.

Patent DE-3238030-A1 (DE)
Title: Twin-shaft engine
Inventor: WILDANGER ALFRED DIPL ING
IPC: F02B41/00
Filed: 1982-10-14
Abstract: The invention relates to a reciprocating piston internal combustion engine with two crankshafts (1) which are arranged in parallel, rotate in opposite directions and are each connected by connecting rods (3) to a common piston (5), either to a common gudgeon pin (4), which can be designed as a rocker lever (Fig. 3) or by means of two gudgeon pins (Fig. 4). Given an appropriate direction of rotation of the crankshafts (1), the angular motion of the connecting rods (3) relative to one another results in a rotary phase of the crankshafts (1) which is prolonged by the angle ( alpha ) during the intake or expansion stroke of the piston (5), while the rotary phase during the exhaust and compression stroke is reduced to the same degree (Fig. 1). Due to the symmetrical arrangement and function of the connecting rods (3), the piston and cylinder wall surfaces are not subjected to side forces. The prolonged intake stroke can be used to improve the charging of the cylinder with fresh gas or fresh air while the prolonged expansion stroke can be used to reduce consumption or increase power. The overall height of the piston can be reduced. <IMAGE>
